Introduction
By using selected emulsifying agents with a suitable emulsion grade penetration bitumen it has been specifically designed for use as a hot applied surface dressing binder.
Conventional non-modified surface dressing binders may lack the cohesive strength necessary to retain chippings under the extra shear stress imposed on road surfaces by vehicles braking or turning sharply. The addition of polymer gives improved properties and enhanced performance.
To aid application SLX 80 has a slight thixotropic nature and excellent breaking properties.
Where to use?
SLX 80 is suitable for use on higher stressed, heavier trafficked sites as a premium grade surface dressing binder as specified in Road Note 39.
Preparation
Please refer to the Road Surface Treatment Association’s (RSTA)/ADEPT Code of Practice for Surface Dressing Part 5 – Surface Preparation.
Application
SLX 80 should be applied at a temperature of 85°C through a bulk binder distributor which has been tested for compliance to BS 1707 (hot binder distributors for surface dressing).
The surface dressing works should be in accordance with the recommendations contained in Design Guide for Road Surface Dressing, Road Note 39 and the RSTA’s Codes of Practice for Surface Dressing.
Due to high residual binder viscosity, optimum results are obtained with SLX 80 during the warmer months of May to August.
Coverage
Refer to the Design Guide for Road Surface Dressing, Road Note 39 or contact our National Sales Office using the details at the back of this brochure for further guidance.
Packaging
Supplied in bulk loads.
Storage
SLX 80 should be stored at 85°C in a purpose-built bulk storage tank or spray tanker and circulated daily. For further information please refer to BS434-2 2006 clause 5.2 storage.
Standards
SLX80 is a CE Marked cationic bitumen emulsion to BS EN13808:2013 C69BPF3/4 or C70BPF3/4.
SLX80 complies with the requirements of Road Note 39, Design Guide for Road Surface Dressing as a Premium Grade surface dressing binder.
